UNITED STATES PATENT OFFICE.

HUBERT SPEETJENS, OF KENSINGTON, LONDO'N, ENGLAND.

APPARATUS FOR PERMANENTLY WAVING THE HAIR.

` To` all whom t may concer/n:

Be it known that HUBERT SPEETJENS, a subject of the Queen of the Netherlands, of 10 Cope Place, Kensington, London, W., England (whose post-o ce address is 10 Cope Place, Kensington, London, W., England), has invented certain new and useful Improvements in Apparatus for Permanently Waving the Hair, of which the following is a specification.

This invention relates to electrically heated apparatus for permanently waving the hair, and is an improvement in apparatus of the type comprising a curler or former upon which the hair is tightly coiled, and a tubular electric heater consisting of a tube on which the electric heating wire is wound and an outer enclosing sleeve or casing. In the practice of the art of hair `waving, it has been found advantageous to be able to regulate the heat applied to the coiled tress or portion of hair on the curler, in order to obtain the greatest heating eli'ect near the roots of the hair and avoid excessive heating, more especially at the outer end of the tress where the hair is naturally thinner and more liable to injury from overheating.

Now according to this invention, the tubular electric heating element is formed preferably adjacent that end which in use is more remote from the roots of the hair, with vent holes, or cooling apertures, or

1 slots capable of being regulated by a rotary or adjustable sleeve or shutter to allow some of the moist heat or steam to escape, the vented part of the element being preferably of larger diameter-,internally than the non-vented part upon which the insulated heating wire is wound.

In the accompanying sheet of illustrative drawings:

Fig. l is an elevation of an electric heater constructed according to this invention,

Fig. 2 is a transverse section of the same taken at 2 2 Fig. l.

lFig. 3 is a longitudinal section taken at 3--3 Fig. 2, and

Fig. 4 is an inverted plan with a part removed.

As shown the tubular heating element consists of an inner tube a which is made of brass or other suitable material and xed to a flanged metal ring b at one end, to

which an annular end piece c of insulating material is attached. Parts of the tube a are cut away as shown at d or the tube may be perforated with annular rows of holes while the heating wire coil is applied at e to an uncut or imperforate part of t-he tube of smaller diameter remote from the handle. An annular space is formed in the part c for the reception of a switch, and is closed by a cover ring or plate c.

Over the inner tube a and heating coil is placed an aluminium tube or sleeve f which is contracted at one end and formed with a series of helical slots g, the outer tube or sleeve f being fixed to the flange of the ring b.

Between the slotted parts of the outer tube f and the inner tube a slotted shutter or sleeve h is interposed, which is capable of being partially rotated by a handle z' to open or close the vent apertures or slots g or regulate them as required. It will be understood that the vent apertures g are not necessarily in the form of slots and that they may take other convenient shapes.

In the permanent hair waving process to which the invention` is applicable, the

.tress of hair when coiled on the curler is wrapped in a cloth or flannel strip moistened with a suitable solution, and over which a cardboard tube is placed. The whole is then inserted in the tubular heating element, the venting of which can be regulated as described by manipulating the movable sleeve or shutter. The connections to the heating coil are led through the annular end piece c and through insulating tubes j, a switch lc being interposed to open and close the circuit.

I claim:

l. A tubular electric heater for hair waving formed with venting apertures or slots capa-ble of being regulated by an adjustable sleeve or shutter.

2. A tubular electric heater for hair'waving comprising an inner tube, an outer tube positioned about said inner tube, said tubes having venting apertures and shutter means between the inner and outer tubes for controlling the apertures of the outer tube.

3. A tubular electric heater for hair waving comprising an inner tube, an outer tube positioned about the inner tube' in spaced relation thereto, and a heating coil positioned only about one end portion of said inner tube.

4. A tubular electric heater for hair Waving comprising an inner tube, an outer tube positioned about. the inner tube in spaced relation thereto, and a heating coil positioned only about one end portion of said inner tube, the remaining portion of the inner tube and the outer tube being provided With venting apertures, and shutter means for controlling the apertures of the outer tube. y

In testimony whereof he has affixed his HUBERT SPEETJENS.
